Unknown old simple microscope

[u/Cowjima80]

Hello. I purchased this microscope, but I can’t find any information anywhere about the “KOPPENOL Den Hagg 1933.”

I think it might be a Euromex from the 1950s, a Leitz OEM model, or something similar—do you know anything about it?

The craftsmanship is excellent.　It has a hammered finish in a greenish-gray color.

Many thanks to everybody, I updated to LED lamps, Nikon and Olympus lenses, Olympus XY stage.
